Description
本發明有關一種多段切換樞軸器，使此類多角度樞軸器可在無需使用額外切換裝置下，進行多段式平整樞軸器的調整轉動。 The invention relates to a multi-section switching pivot, so that the multi-angle pivot can perform the adjustment and rotation of the multi-section flat pivot without using an additional switching device.
筆記型電腦之類電子設備大致上由一主機系統端及一可供掀開的液晶顯示螢幕端所構成，在主機系統端及液晶顯示螢幕端相對端部以樞軸器連接作為動作軸心，使用時能以樞軸器為動作軸心掀開上蓋的液晶顯示螢幕進行操作，或在不使用時反向將兩者相對閉合存放或隨身攜帶備用。 An electronic device such as a notebook computer is generally composed of a host system end and a liquid crystal display screen which can be opened. The host system end and the opposite end of the liquid crystal display screen are pivoted as the axis of action. When in use, the pivot can be used as the axis of action to open the upper lid of the liquid crystal display screen for operation, or when not in use, the two are relatively closed and stored in opposite directions or can be carried with them for future use.
此類筆記型電腦可透過雙軸樞軸器的設置，使顯示端及系統端能彎折成各種不同的操作角度，甚至彎折360°成為互疊的平板狀，提供一類如平板電腦的操作及使用型態。 This type of notebook computer can be equipped with a dual-axis pivot device to enable the display end and the system end to be bent into various operating angles, and even bent 360 ° into an overlapping flat shape, providing a type of operation such as a tablet computer And usage patterns.
現有使用雙軸式樞軸器的結構主要是具有一第一轉軸與顯示端一同轉動，及一第二轉軸與系統端一同轉動。但現有此類使用雙軸式的樞軸器在打開較大角度，或要使顯示端及系統端翻折360°的互疊狀態時，通常先使其中一軸旋轉到特定角度後，再切換至另一軸旋轉。 The existing structure using a dual-axis pivot device mainly has a first rotating shaft rotating with the display end, and a second rotating shaft rotating with the system end. However, when such a current type of dual-axis pivot is used to open a large angle, or when the display end and the system end are folded 360 ° in an overlapping state, usually one of the axes is rotated to a specific angle before switching to The other axis rotates.
在現有此類雙軸式樞軸器的翻折控制機構中，通常使用套設在軸身上的切換片來控制一軸轉動到設定角度後，再切換到另一軸，由於所述的切換片設置在作動機構的軸向位置，來進行軸向移動控制，相對會 使整個樞軸器的長度增加，而不利於樞軸器整體長度的小型化設計。 In the existing folding control mechanism of such a double-shaft pivot device, a switching piece set on the shaft body is usually used to control one axis to rotate to a set angle and then switch to another shaft. The axial position of the actuating mechanism to control the axial movement will relatively increase the length of the entire pivot, which is not conducive to the miniaturized design of the overall length of the pivot.
隨後雖有可減小上述切換片軸向長度的樞軸器設計，但基本上仍須使用該切換裝置，而有使構件複雜化及使整個樞軸器動作穩定度受到影響的缺點產生。同時，此類多段轉動式雙軸樞軸器由閉合狀態翻轉到360°過程中，會產生雙軸位移變化，特別是在翻轉到180°左右位置時，整個樞軸器會突出於電子設備攤平狀態下的表面，而使此類電子設備難以平整的放置在桌面。 Later, although there is a pivot design that can reduce the axial length of the above-mentioned switching piece, the switching device must basically be used, and there are disadvantages that complicate the components and affect the stability of the entire pivot operation. At the same time, during the process of turning such a multi-segment rotary biaxial pivot from a closed state to 360 °, a biaxial displacement change will occur, especially when it is turned to a position of about 180 °, the entire pivot will protrude from the electronic equipment booth. The flat surface makes it difficult for such electronic devices to be placed flat on a desktop.

第4圖顯示本發明切換機構在閉合狀態位置，此時上述第一凹凸輪組40的一側中間凸輪43上凸部433壓接於一側上凹輪41的短凹弧411，下凸部434則壓接於一側下凹輪42的外周緣；上述第二凹凸輪組60則使上凸部633壓接於另側上凹輪61的外周緣，下凸部634則壓接於另側下凹輪62長凹弧621的其中一端定位凹部6211，同時，使上述另側上凹輪61的下止擋肩部613擋靠於上述中間定位隔板50的上定位凸點52，並使上述另側下凹輪62的上止擋肩部622擋靠於上述中間定位隔板50的下定位凸點53。此時，整個樞軸器的狀態位置如第1圖所示。 FIG. 4 shows the switching mechanism of the present invention in a closed state position. At this time, the convex part 433 on the middle cam 43 on one side of the first concave-convex wheel set 40 is crimped to the short concave arc 411 and the convex part on the concave wheel 41 on one side. 434 is crimped to the outer periphery of the concave wheel 42 on one side; the second concave-convex wheel set 60 is configured to crimp the upper convex portion 633 to the outer periphery of the upper concave wheel 61 on the other side, and the lower convex portion 634 is crimped to the other One end of the long concave arc 621 of the side concave wheel 62 locates the concave portion 6211, and at the same time, the lower stop shoulder portion 613 of the other upper concave wheel 61 is abutted against the upper positioning bump 52 of the intermediate positioning partition 50, and The upper stop shoulder 622 of the lower concave wheel 62 is abutted against the lower positioning bump 53 of the intermediate positioning partition 50. At this time, the state and position of the entire pivot is shown in FIG. 1.
如第5圖所示，當上述第二軸20以逆時針方向反轉一角度(如100°)進行第一段轉動時，上述第一凹凸輪組40的一側下凹輪42轉成使長凹弧421朝上，使一側中間凸輪43上凸部433可脫離一側上凹輪41的短凹弧411，並準備下降使下凸部434進入一側下凹輪42的長凹弧421一端定位凹部4212(附參第6圖)；上述第二凹凸輪組60於此一轉動過程中則使另側中間凸輪63的下凸部634沿著長凹弧621由一端定位凹部6211移動到另端定位凹部6212，完成第一段轉動過程，此時整個樞軸器的轉動狀態如第5A圖所示。如第6圖所示，上述第一軸10能接著以順時針方向正轉一角度(如180°)進 行第二段轉動，使上述第二凹凸輪組60因另側上凹輪61的轉動，使上止擋肩部612移靠到中間定位隔板50的上定位凸點52，此時，另側上凹輪61的短凹弧611朝向另側中間凸輪63的上凸部633，使另側中間凸輪63處於釋放狀態，同時使一側中間凸輪43受力下降進入一側下凹輪42長凹弧421的其中一端定位凹部4212，此時整個樞軸器的轉動狀態如第6A圖所示，由第5A圖所示的100°夾角經過幾乎是平整狀態的180°後，形成260°夾角。如第7圖所示，然後可再將上述第二軸20以逆時針方向反轉一角度(如80°)進行第三段轉動時，直到第二凹凸輪組60的另側下凹輪62由第二段轉動過程的長凹弧621另端定位凹部6212的位置移動到使下止擋肩部623抵靠於上述中間定位隔板50的下定位凸點53，於此一過程中，另側中間凸輪63受力上升，使上凸部633壓靠於另側上凹輪61的短凹弧611。此時，整個樞軸器的狀態位置如第7A圖所示，成為360°互疊平板狀。反之，則可依上述多段動作的反向程序，將第一軸10及第二軸翻折回第1圖及第4圖所示的0°夾角關閉狀態。 As shown in FIG. 5, when the second shaft 20 is rotated counterclockwise by an angle (eg, 100 °) for the first rotation, the lower concave wheel 42 on one side of the first concave-convex wheel group 40 is turned into The long concave arc 421 faces upward, so that the convex part 433 of the intermediate cam 43 on one side can be separated from the short concave arc 411 of the concave wheel 41 on one side, and the lower convex part 434 is prepared to enter the long concave arc of the concave wheel 42 on one side. 421 positioning concave portion 4212 at one end (see FIG. 6 of the attached reference); during the rotation of the second concave-convex wheel set 60, the lower convex portion 634 of the other intermediate cam 63 moves along the long concave arc 621 from the positioning concave portion 6211 at one end Go to the positioning recess 6212 at the other end to complete the first stage of rotation. At this time, the rotation state of the entire pivot is shown in Figure 5A. As shown in FIG. 6, the first shaft 10 can then rotate clockwise for an angle (such as 180 °) for the second rotation, so that the second concave-convex wheel set 60 is rotated by the concave wheel 61 on the other side. The upper stop shoulder 612 is moved to the upper positioning bump 52 of the intermediate positioning partition 50. At this time, the short concave arc 611 of the other upper concave wheel 61 faces the upper convex portion 633 of the other intermediate cam 63, so that On the other side, the intermediate cam 63 is in a released state, and at the same time, the intermediate cam 43 on one side is lowered into the concave recess 4212 on one end of the long concave arc 421 on the one side of the concave wheel 42. At this time, the entire pivoting state is as shown in FIG. 6A As shown, the angle of 100 ° shown in FIG. 5A passes through 180 °, which is almost flat, to form an angle of 260 °. As shown in FIG. 7, the second shaft 20 can then be rotated counterclockwise by an angle (such as 80 °) for the third rotation until the other concave wheel 62 of the second concave-convex wheel group 60 The position of the positioning recess 6212 at the other end of the long concave arc 621 at the second stage of rotation is moved to make the lower stop shoulder 623 abut the lower positioning bump 53 of the intermediate positioning partition 50. In this process, another The side intermediate cam 63 is forced to rise, so that the upper convex portion 633 is pressed against the short concave arc 611 of the upper concave wheel 61 on the other side. At this time, the state and position of the entire pivot is shown in Fig. 7A, and becomes 360 ° overlapping flat plates. Conversely, the first axis 10 and the second axis can be turned back to the 0 ° included angle closed state shown in Figs.
本發明因而形成一種多段切換樞軸器，在無需使用切換片或切換銷之類切換裝置下，可進行多段式的樞軸器角度轉動調整，不僅可簡化此類樞軸器的構成元件，縮小整個樞軸器的軸向長度，更有利於使樞軸器在進行如180°角度位移時平躺，與攤開的電子設備的螢幕顯示端及系統端保持平整狀態供放置在桌面。 The invention thus forms a multi-section switching pivot, which can perform multi-stage pivot adjustment of the angular rotation without using a switching device such as a switching piece or a switching pin, which can not only simplify the constituent elements of such a pivot, but also reduce the size. The axial length of the entire pivot device is more conducive to making the pivot device lie flat when performing an angular displacement such as 180 °, and maintain a flat state with the screen display end and the system end of the spread electronic device for placement on a desktop.
